Detections ranked by share of the limitevery Tier 1 detection, highest first
Bar length is the highest result in the last 36 months as a share of the federal limit (MCL, or action level for lead and copper). The dark tick marks the limit. Gross alpha is compared after subtracting uranium, as DEQ does for compliance.

- Copper: 90th percentile of samples taken at customer taps. Results depend on the home's plumbing.
- Gross Alpha: Compliance uses the running average of gross alpha minus uranium. Shown value is the highest lab result; the adjusted average is 0.0 pCi/L after subtracting 32.71 pCi/L for uranium.
- Lead: 90th percentile of samples taken at customer taps. Results depend on the home's plumbing.
ppb = parts per billion (µg/L), ppm = parts per million (mg/L), ppt = parts per trillion. ND = not detected above the lab's reporting limit. MCL = federal maximum contaminant level; AL = action level for lead and copper (90th percentile of home taps); aesthetic = secondary standard for taste, odor or staining, not health. Bars show the highest result in 36 months as a share of the limit.

Hardness
Hardness is not reported in the latest CCR. Hardness not reported for this system; softener sizing uses a regional default of 11.7 gpg until a CCR value is reviewed.

No health-based violations (MCL, treatment technique, or disinfectant level) in the last ten years.
Monitoring and reporting violations (12)
A required sample or report was late or missing. These do not mean a contaminant was found, but a system that skips monitoring has gaps in its record.

Lead and copper at the tap90th percentile of sampled homes against the action level
90th percentile of samples taken at customer taps. Results depend on the home's plumbing. Results are from sampled homes in this system, not from your tap. Home plumbing can add lead and copper. First-draw samples run higher than flushed ones.

Questions about Sunlight Terrace
Is Sunlight Terrace tap water safe to drink?
In the last 36 months at least one result for Sunlight Terrace was above a federal limit: Uranium. A single high sample is not always a violation because compliance is often judged on a running average; the violations section shows what EPA recorded. Results reflect the system's sampling points, not the plumbing in any one home.
Is Sunlight Terrace water hard?
Hardness has not been reported for Sunlight Terrace in a reviewed Consumer Confidence Report yet. The softener sizing widget uses a labelled county default until a report is reviewed.
Is Sunlight Terrace water fluoridated?
No fluoride result in the last 36 months.
Where does Sunlight Terrace water come from?
Sunlight Terrace draws from 2 active wells with 64 treatment plants on record. Source and treatment details are listed above.
What filter fits Sunlight Terrace water?
For drinking water the matching engine ranks Aquasana OptimH2O Reverse Osmosis + Claryum first for this profile, based on certified reduction claims for the contaminants flagged above. See the filters section for the reasoning and alternatives.
What was above the limit in Sunlight Terrace water?
Uranium. Compare the value with the limit in the ranked chart and the full report above, and check the violations section for whether EPA recorded a violation.
